The inquiry into charges against trainer Jarrod McLean possessing a banned electric-shock device was adjourned until September after a brief appearance before the Racing Appeals and Disciplinary Board on Monday.

McLean, who has continued to train and has three runners at Ballarat Synthetic on Tuesday, faces two charges — possessing an electrical apparatus, known as a jigger, and conduct prejudicial to racing.

The charges arose from the January raids by Racing Victoria stewards, and Victoria police, that resulted in trainer Darren Weir receiving a four-year ban after a jigger was found in his bedroom.

Weir didn’t contest his charges, but McLean, who had been Weir’s assistant while also training on his own, has opted to proceed with a hearing.
